Organic biological fertilizer can activate and improve the soil, enhance the resistance to disease, insect and disaster of crops, and improve the quality and yield of crops(105 cell propagation trays wholesale). At the same time, combining with the fourth instar of silkworms, we should carry out mulberry heartpicking to improve the yield and quality of mulberry leaves and ensure the production of leaves for spring silkworms(plant start trays wholesale). The plant ash is a kind of alkaline fertilizer.

In addition, ammonium sulfate, ammonium nitrate and ammonium bicarbonate are all ammonium nitrogen fertilizers(gallon pot). If they are mixed with plant ash, the nitrogen in the nitrogen fertilizer will become ammonia and run away. When using plant ash and acid fertilizer at the same time, be sure not to mix them together(24 cell propagation trays wholesale). It is a mistake in the countryside to put the ashes of plants and trees into a pit or a pigsty for storage.(cheap plastic cell seedling trays suppliers in italy)
After the sampling point is determined(seed starting trays), more nitrogen and potassium fertilizer are needed in the early growth stage; livestock manure and human manure are a kind of slow effect acid nitrogen fertilizer, such as pouring alkali plant ash into the acid livestock manure and human manure, neutralizing acid and alkali to volatilize ammonia, so as to reduce the fertilizer efficiency(20 cell propagation trays wholesale). It is very important to apply calcium fertilizer to the cracked fruit of peaches.
(cheap plastic cell seedling trays suppliers in italy)The samples used for mutual comparison shall be collected at the same time, and the sampling positions shall be fixed and consistent(square grow pots). When trace element analysis is carried out, the straw pile will be covered with soil or covered with waste plastic film, and the compost will be about 10 days; stainless steel grinder or ceramic mortar shall be used for grinding(288 cell propagation trays wholesale). All kinds of smoke and dust pollution shall be avoided during the treatment.
After corn harvest, the green body of straw will be smashed on the spot and piled up in piles along with the harvest(plastic plant pots wholesale suppliers); 2 kg biochemical agent and 5 kg urea (or a certain amount of human and animal manure) will be added for every 1000 kg straw, and water will be supplemented appropriately according to the moisture content of straw(112 cell propagation trays wholesale); the straw after composting will be spread and ploughed into the soil to make wheat basal fertilizer.
This is mainly due to the lack of calcium. Peaches are particularly sensitive to calcium(plastic plant trays wholesale). Calcium deficiency not only makes the ventral line soft and rotten, but also reduces the hardness, taste and storage capacity of peaches as a whole. There are two ways of calcium absorption, one is root absorption, the other is leaf absorption(200 cell propagation trays wholesale). In recent years, many fruit farmers use a lot of immature organic fertilizer, especially chicken manure.(cheap plastic cell seedling trays suppliers in italy)
After the organic fertilizer is applied into the soil without fermentation(98 cell propagation trays wholesale), it will produce a lot of heat in the fermentation process, burn the tender absorption root, make the tree weak and premature aging, even death, and also affect the absorption of calcium(162 cell propagation trays wholesale). The following four points should be paid attention to in the process of use and preservation: the plant ash is an alkaline fertilizer and should not be mixed with ammonium sulfate and ammonium nitrate.
(cheap plastic cell seedling trays suppliers in italy)The effect of foliar calcium supplement is not obvious(cheap plastic plant pots bulk). When the climate is hot and rainy, in order to avoid nutrient loss, it is necessary to master the principle of applying a small amount of fertilizer frequently. When the climate is cold, greatly affect the absorption capacity of the root, apply the organic fertilizer which has been fully decomposed as top dressing(128 cell propagation trays wholesale). Plant ash should not be mixed with human manure and livestock manure.
